The BAU is called to investigate the murder of two small-town high school students in McAllister, Virginia, who may have been victims of a cult killing. Based on the crime scene evidence, the team begins to believe it is possible that someone other than a cult member may be responsible.

Competition arrives for Swearengen in the form of the Bella Union, a new gambling outfit from Chicago operated by savvy Cy Tolliver, Madame Joanie Stubbs and gaming guru Eddie Sawyer. Hickok puts up precious collateral in a poker game with McCall; Bullock and Star strike a deal with Swearengen on a lot for their store and, with help from Hickok and Utter, set to building; Brom threatens Swearengen with the Pinkertons before he and Dan Dority are dispatched to reconnoiter his claim.

Swearengen transforms the Gem into a courtroom as Deadwood is forced to make its own laws to try a cowardly murderer. With Jane off on a bender, Trixie is enlisted by Swearengen to help Alma with the Metz child and to keep her pliable to his purposes; Doc Cochran fears Cramed's illness might threaten the camp; Tolliver sends Cramed to take the air in the woods, where he meets Jane. Feeling that justice hasn't been served, Bullock decides to take the law into his own hands.

After tracking down a murderer, Bullock returns to Deadwood a changed man--and a marked one--while Utter must pay final respects to a fallen friend. Dority and Stubbs both take special interest when teenagers Miles and Flora Anderson arrive in camp in search of their father, each finding work at a rival saloon; Calamity Jane earns her moniker in the Pest Tent; Swearengen sees through Trixie's latest subterfuge; and Alma remains cold on Farnum's inappropriately advanced bid on her claim.

Raylan squares off with a pair of merciless Detroit hitmen. The battle between Boyd and Quarles comes to a head.
